Özet

Bu çalışmada, asetofenon (Ia-j) ve benzaldehit (IIa-d) türevlerinin metanol içinde KOH varlığında reaksiyonu ile şalkon türevleri (IIIa-u) elde edilmiş, elde edilen şalkonların etanol içinde hidrazit türevleriyle (IVa-f) ısıtılmasıyla hidrazon (Va-s) ve 2-pirazolin (VIa-u) yapısında bazı yeni moleküllerin sentezleri gerçekleştirilmiştir. Böylece şalkon (2), hidrazon (18) ve 2-pirazolin (20) türevleri olan toplam 40 orijinal kimyasal madde elde edilmiş ve bunların yapı tayinlerinde Elementel Analiz, IR, 1H-NMR ve Mass spektral yöntemlerinden yararlanılmıştır. Sentezlenen bileşiklerin, MAO enzimi üzerindeki inhibisyon yapıcı etkileri incelenmiş ve sonuçta VIa, VIc, VIf ve VIl bileşiklerinin referans bileşik moklobemide yakın düzeyde MAO-A enzimi üzerinde inhibisyon yapıcı etki gösterdikleri saptanmıştır.

Özet (Çeviri)

In this study, chalcone derivatives (IIIa-u) were prepared with the reaction of some acetophenone (Ia-j) and benzaldehyde derivatives (IIa-d) in KOH/MeOH. The ensuing chalcone derivatives (IIIa-u) are then reacted with some hydrazide compounds to furnish hydrazone (Va-s) and 2-pyrazoline (VIa-u) derivatives. The structure of synthesized original chalcone (2), hydrazone (18) and 2-pyrazoline (20) derivatives was elucidated by IR, 1H NMR, Mass spectral data and elementary analysis findings. The synthesized compounds were tested for their MAO inhibitor activities and it is found that compounds VIa, VIc, VIf and VIl have similar activities as moclobemide. Chemical names of synthesized compounds are given below;IIIc (E)-1-(3,5-Dichloro-2-hydroxyphenyl)-3-m-tolylprop-2-en-1-oneIIIo (E)-1-(4-Bromophenyl)-3-m-tolylprop-2-en-1-onVa (E)-N'-((E)-1-(2,4-Dimethoxyphenyl)-3-p-tolylallylidene)thiophene-2-carbohydrazideVb (E)-N'-((E)-1-(2,4-Dimethoxyphenyl)-3-p-tolylallylidene)furan-2-carbohydrazideVc (E)-N'-((E)-1-(4-Fluorophenyl)-3-(4-methoxyphenyl)allylidene)thiophene-2-carbohydrazideVd (E)-N'-((E)-1-(4-Fluorophenyl)-3-(4-methoxyphenyl)allylidene)-4-methyl-1,2,3-thiadiazole-5-carbohydrazideVe (E)-N'-((E)-1-(4-Fluorophenyl)-3-p-tolylallylidene)thiophene-2-carbohydrazideVf (E)-N'-((E)-1-(4-Fluorophenyl)-3-m-tolylallylidene)thiophene-2-carbohydrazideVg (E)-N'-((E)-1-(4-Bromophenyl)-3-p-tolylallylidene)thiophene-2-carbohydrazideVh (E)-N'-((E)-1-(4-Bromophenyl)-3-p- tolylallylidene)-4-methyl-1,2,3-thiadiazole-5-carbohidrazideVi (E)-N'-((E)-1-(4-Bromophenyl)-3-(4-methoxyphenyl)allylidene)-4-methoxy benzohydrazideVj (E)-N'-((E)-1-(4-Bromophenyl)-3-m-tolylallylidene)-4-methyl-1,2,3-thiadiazole-5-carbohidrazideVk (E)-N'-((E)-1-(4-Bromophenyl)-3-(4-methoxyphenyl)allylidene)furan-2-carbohydrazideVl (E)-N'-((E)-1-(4-Chlorophenyl)-3-p-tolylallylidene)thiophene-2-carbohydrazideVm (E)-N'-((E)-1-(4-Chlorophenyl)-3-p-tolylallylidene)-4-methyl-1,2,3-thiadiazole-5-carbohidrazideVn (E)-N'-((E)-1-(4-Chlorophenyl)-3-m-tolylallylidene)-4-methyl-1,2,3-thiadiazole-5-carbohidrazideVo (E)-N'-((E)-1-(4-Chlorophenyl)-3-(4-metoxyphenyl)allylidene)-4-methyl-1,2,3-thiadiazole-5-carbohidrazideVp (E)-N'-((E)-1-(4-Chlorophenyl)-3-(4-metoxypheny)allylidene)-4-metoxybenzohidrazideVr (E)-N'-((E)-1-(4-Hydroxyphenyl)-3-p-tolylallylidene)-4-methyl-1,2,3-thiadiazole-5- carbohidrazideVs (E)-N'-((E)-1-(4-Metoxyphenyl)-3-p-tolylallylidene)-4-methyl-1,2,3-thiadiazole-5-carbohidrazideVIa(3-(5-Chloro-2-hidroxyphenyl)-5-p-tolyl-4,5-dihydropyrazole-1-yl)(pyridine-4-yl) methanoneVIb (3-(5-Chloro-2-hidroxyphenyl)-5-p-tolyl-4,5-dihydropyrazole-1-yl)(furan-2- yl)methanoneVIc (3-(5-Chloro-2-hydroxyphenyl)-5-p-tolyl-4,5-dihydropyrazole-1-yl)(phenyl) methanoneVId (3-(5-Chloro-2-hydroxyphenyl)-5-p-tolyl-4,5-dihydropyrazole-1-yl)(4-metoxyphenyl) methanoneVIe (3-(5-Chloro-2-hydroxyphenyl)-5-p-tolyl-4,5-dihidropyrazole-1-yl)(4-methyl-1,2,3-thiadiazole-5-yl)methanoneVIf (3-(3,5-Dichloro-2-hydroxyphenyl)-5-p-tolyl-4,5-dihydropyrazole-1-yl)(4-metoxyphenyl) methanoneVIg (3-(3,5-Dichloro-2-hydroxyphenyl)-5-m-tolyl-4,5-dihidropyrazole-1-il)(pyridine-4-il) metanoneVIh (3-(3,5-Dichloro-2-hydroxyphenyl)-5-m-tolyl-4,5-dihidropyrazole-1-yl)(furan-2-yl) methanoneVIi (3-(3,5-Dichloro-2-hydroxyphenyl)-5-m-tolyl-4,5-dihydropyrazole-1-yl)(phenyl) methanoneVIj (3-(3,5-Dichloro-2-hydroxyphenyl)-5-m-tolyl-4,5-dihydropyrazole-1-yl)(4-metoxyphenyl) methanoneVIk (3-(3,5-Dichloro-2-hydroxyphenyl)-5-m-tolyl-4,5-dihydropyrazole-1-yl)(4-methyl-1,2,3-thiadiazole-5-yl)methanoneVIl (3-(5-Bromo-2-hydroxyphenyl)-5-p-tolyl-4,5-dihydropyrazol-1-yl)(pyridine-4-yl)methanoneVIm (3-(5-Bromo-2-hydroxyphenyl)-5-p-tolyl-4,5-dihydropyrazol-1-yl)(furan-2-yl) methanoneVIn (3-(5-Bromo-2-hydroxyphenyl)-5-p-tolyl-4,5-dihydropyrazol-1-yl)(phenyl)methanoneVIo (3-(5-Bromo-2-hydroxyphenyl)-5-p-tolyl-4,5-dihydropyrazol-1-yl)(4-metoxyphenyl) methanoneVIp (3-(5-Bromo-2-hydroxypheny)-5-p-tolyl-4,5-dihydropyrazol-1-yl)(thiophene-2-yl) methanoneVIr (3-(2-Hydroxy-4-metoxyphenyl)-5-(2-metoxyphenyl)-4,5-dihydropyrazol-1-yl)(phenyl) methanoneVIs (3-(2-Hydroxy-4-metoxyphenyl)-5-(4-metoxyphenyl)-4,5-dihydropyrazol-1-yl)(4-metoxyphenyl)methanoneVIt (3-(5-Bromo-2-hydroxyphenyl)-5-(4-metoxyphenyl)-4,5-dihydropyrazol-1-yl)(4-metoxyphenyl)methanoneVIu (3-(5-Chloro-2-hydroxyphenyl)-5-(4-metoxyphenyl)-4,5-dihydropyrazol-1-yl)(thiophen-2-yl) methanone
